 ### Breaking:
-Nothing.
+Protocols:
+- Valve:
+due to some games being able to host a server from within the game AND from a dedicated server, 
+if you were to query one of them, the query would fail for the other one, as the `SteamID` enum
+for that game could specify only one id.
+1. `SteamID` is now `SteamApp`, was an u32 enum, and now it's a simple enum.  
+2. `App` is now `Engine`, the `Source` enum's structure has been changed from `Option<u32>` to
+`Option<u32, Option<u32>>`, where the first parameter is the game app id and the second is
+the dedicated server app id (if there is one).
